Clay can be found virtually everywhere in the world. However, many regions in the world produce large quantities of specific types of clay. Brazil, the United Kingdom and the United States all produce kaolin clay while Germany, Turkey, Greece produce bentonite clay.
The United States produces many different types of clay, including kaolin clay, ball clays, fire clays, bentonite, and Fuller's earth clay. The country produces large quantities of each of these clay types and, consequently, does not require import of much clay; the United States exports more than half of its clay each year to countries all around the world.
